Application filed August 24, 1903. Renewed January 6, 1905. Serial No. 239,888.

To all whom, it may concern,.-

Be it known that I, JOHN LUGIN ADAM, a citizen of the United States, and a resident of New Orleans, Orleans parish, State of Louisiana, have invented certain new and useful Improvements in Heaters and Cookers, and my preferred manner of carrying out the inn vention is set forth in the following full, clear, and exact description, terminating with a claim particularly specifying the novelty.

This invention relates to stoves and furnaces, and more especially to that class of devices which are intended forheating water, although the construction herein described produces a stove for cooking and for heating purposes.

The gist of this invention consists in the use, with other necessary elements, of a heat retainer and deflector by which the products of combustion are retained sufficiently to cause this element to be useful as a heater or oven, radiating its heat in all directions and deflecting the products ofl combustion toward or directly against an adjacent chamber (and the cooking utensils, if any are located in that chamber), and thence outward into the room. l

In the drawings, Figure I is a vertical section through the entire device, showing in elevation a gas inlet, a water outlet, and one of the pots in place. Fig. II is a plan view of one form of heater. Eig. III is a bottom plan view of the water chamber, showing the coil which may be used therein. Fig. IV is a bottom plan view of the oven with the door swung open. Fig. V is a section through the water chamber on a line at right angles to the section of Fig. I. Fig. VI is a detail of one of the post 4omitting the elbow in its handle.

In the accompanying drawings the main parts of this device are the heating chamber, the water chamber, the cooking pots, and the heat retainer and deiiector usually having the form of an oven. These parts will now be described in detail.

The heating chamber here shown comprises a casing 1 with suitable air inlets 2, and within this casing at its center in one form of the invention is supported a heater 3. In the present instance this is a gas burner, although other fuel could be used. The gas is here supplied through pipe 4, and 5 is the air mixer usually employed so as to produce a blue flame.

6 is the pilot light for igniting the burner.

No novelty is claimed for the construction of the heater, nor for the exact construction of the heating chamber itself although this portion of the device is considered useful in conjunction with the other parts.

The water chamber comprises an opentopped shell 10 whose bottom 11 is raised so that the shell may fit over casing 1 of the heating chamber; and rising through the center of this bottom is a flue 12 to carry upward the heat generated by the burner. Below the bottom 11 and secured in close contact therewith is here shown a coil 13, as best seen in Fig. III. Cold water is admitted to this coil through the inlet valve 14 which is placed in one end of the coil that protrudes through the shell and is bent upward as is best seen in Fig. V. This inlet is above the level of the whole coil and Valso above the bottom 11. Water may be fed through the inlet in any suitable manner. At its other end the coil passes upward through the bottom 11, and has its outlet 15 directly into the interior of the water chamber. When the parts are assembled as shown in Fig. I the straight portion of coil 13 fits within notch 130 in the u per edge of the burner chamber (see Fig. IPI). Preferably arranged quartering to the cold water inlet 14 is the hot water outlet or faucet 16. As shown, this faucet stands above the level of the bottom of the water chamber, and also above the whole of the heating coil. There may be two such faucets, the second indicated at 17in dotted lines in Fig. V. With two faucets, one quite high the other quite low, hot water could always be drawn out of the lower one, while the upper one could be left open to prevent the water from overflowing. Or the ordinary water gage might be employed for this purpose.

It will be clear that the cold water when led in the direction indicated passes -first through the hot coil where it becomes heated, then rises into the chamber the hot bottom of which maintains the heat .of the water, then rises within the body of the chamber whose central flue still maintains the heat, and 'finally is drawn off as desired. It will also be clear that the water could be fed into and withdrawn from the chamber in the reverse direction-the above described faucet 16 being used as the inlet and the above Adescribed valve 14 being used as the outlet. This course may sometimes be preferred, and

IIO

in any event it is a convenient means of washing outv the coil. This arrangement effects a safety device, whereby the bottom and the coil are always provided with a body of water and hence prevented from burning out. If the faucet 16 is open, the water within the chamber will obviously fall until the level of the faucet is reached, leaving plenty of water within the coil and a continuation of the same body above the bottom. On the other hand, suppose faucet 14 to be open, either by accident or design as before the water will fall until the level of this faucet is reached; but this level is considerably above both the bottom and the coil. The utility of this arrangement will be apparent when it is considered that the device will frequently be used when it is impossible or inconvenient to make connections with a source of water under pressure through either of faucets 14 or 16. In this case water might be poured in through the open top of the water chamber and even though both faucets were open, sufficient liquid would be trapped in the coil and water chamber to prevent burning. And even if no water were added, there would be sufficient liquid standing in the heater to prevent injury.

The cooking utensils or double boilers used in connection with this device when the latter is cylindrical as shown, are preferably sector-shaped pots as best seen in Fig. VI. Each comprises a body 20 with a fiat bottom and an open top, a cover 2l for closing the latter, and a handle 22 which is preferably provided with an elbow or bend 23. The inner corner of the body instead of forming an angle is bent in as at 24. Of course there might be two pots, or three or-more; but I preferably employ four, each occupying about a quarter of a circle. When in place within the chamber the elbow is hooked over the upper edge of the shell 10 which holds the bend 24 of the body slightly remote from the central flue and lifts the bottom of the pot slightly above the bottom of the chamber. `he purpose of this, and hence the function of the elbow, is to cook the contents of each pot by the hot water bath process so as to prevent burning.

The heat retainer and deflector may be of any proper shape and size, but as shown herein it is a drum comprising a cylindrical shell 30 with a top and bottomkthus constitutin the retainer. This device has openings epending on its use. If it is to be used as an oven, it may have a removable cover 31, or one or more doors 83 in its sides, or both. These are for access to itsv interior, and when they are closed the device is strictly a heat retainer. If it is to be used as a heater, these openings are closed or may be omitted, but there are perforations 32, preferably in its bottom, for the escape of heatthus constituting the deflector. Secured to the bottom around a central perforation therein is a sleeve 34 which is adapted to be slipped over the upper end of the flue 12. The sleeve may be made of such internal diameter as to iit tightly onto the flue, so that it can be adjusted upon the latter to a greater or less height above the water chamber and pots, or the oven may be held in place in any suitable manner. The sleeve 40 shown in Fig. V differs from that in Fig. I in having its upper end split into arms which are bent outward and serve as supports for the heat retainer and deflector. By slipping the sleeve down on the iiue to the extent shown in Fig. I, the top of the heat retainer and deiiector will be brought so close to the upper end of the flue as to retard the outlet of heat, thereby restricting the free escape of the products of combustion and causing them to accumulate beneath the water chamber. This or any suitable means for controlling the passage of heat by partially closing the Hue will intensify the heat it contains and increase its power for radiation; but if the flue be completely closed the heat will accumulate beneath the Water chamber and finally find its exit through holes in the shell of the heating chamber hence no injury to the apparatus will result. The products of combustion trapped within the heating chamber or the heat received from the burner pass upward into the oven and cook its contents while thoroughly heating its top, sides, and bottom; and from the oven the heat is radiated upward and outward, as well as downward upon the cooking utensils or upon the Water in the water chamber. If the perforations are in the bottom, the products of combustion find their exit downward through the holes 32 onto the tops of the pots if they are used, but in any event rise around the outside of the oven which is thus heated internally and externally, and pass off into the room which is heated thereby. It is well known that no bad odors or results accrue from the burning of ordinary illuminating gas when mixed with air by the Bunsen or blue type of burner, and hence I consider it desirable that the heating chamber shall trap the heat from a generator of the gasburner type. It will be seen that when the pots are used, they receive heat from the water chamber, flue, and oven.

All parts are preferably of metalmainly sheet iron which may be japanned or galvanized. The fittings might well be of brass. I have shown the device as circular in contour although it might be square or oval or of other shape.
